[1] During the nine months ended July 2, 2022, the Company recognized a reduction in revenue for amounts to early terminate certain license agreements with a customer for film and television content, which was delivered in previous years, in order for the Company to use the content primarily on our direct-to-consumer services (Content License Early Termination). Because the content is functional intellectual property (IP), we recognized substantially all of the consideration to be paid by the customer under the licenses as revenue in prior years when the content was made available under the agreements. Consequently, we have recorded the amounts to terminate the license agreements, net of remaining amounts of deferred revenue, as a reduction of revenue in the current nine-month period.
